Crf450/400ex hybrid ?'s!!!!!!!!!!!

[jason450]

Hey guys im about to buy a 400ex frame with a 03 crf450 motor all race ready and everything. The guy clames it over heats every once in a while, and that this happens when you put these motors in these frames. What can I do to keep it cool? Is there a kit?

Any help would be great ! Thanks guys

a frame would not a motor to overheat. unless, the frame is so heavy it is putting a load on the motor that it was not designed to take.

get an intense fab or PWR radiator, some air scoops, run engine ice, and try not to sit around forever just letting it idle..... you wont have any problems.
